What is frovatriptan?
Frovatriptan is a headache medicine that narrows blood vessels around the brain. Frovatriptan also reduces substances in the body that can trigger headache pain, nausea, sensitivity to light and sound, and other migraine symptoms.
Frovatriptan is used to treat migraine headaches. Frovatriptan will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.
Frovatriptan should not be used to treat a common tension headache, or a headache that causes loss of movement on one side of your body. Use frovatriptan only if your condition has been confirmed by a doctor as migraine headaches.
Frovatriptan may also be used for purposes not listed in this medication guide.
You should not use frovatriptan if you have ever had heart disease, coronary artery disease, blood circulation problems, Wolff-Parkinson-White syndrome, uncontrolled high blood pressure, severe liver disease, a heart attack or stroke, or if your headache seems to be different from your usual migraine headaches.
Do not take frovatriptan within 24 hours before or after using another migraine headache medicine.
Before taking this medicine
You should not use frovatriptan if you are allergic to it, if you have a headache that seems different from your usual migraine headaches, or if you have ever had:
heart problems, or a stroke (including “mini-stroke”);
coronary artery disease, angina (chest pain), blood circulation problems, lack of blood supply to the heart;
circulation problems affecting your legs, arms, stomach, intestines, or kidneys;
a heart disorder called Wolff-Parkinson-White syndrome;
uncontrolled high blood pressure; or
severe liver disease.
Tell your doctor if you have ever had:
liver or kidney disease;
high blood pressure, a heart rhythm disorder; or
risk factors for coronary artery disease (such as diabetes, menopause, smoking, being overweight, having high blood pressure or high cholesterol, having a family history of coronary artery disease, or being older than 40 and a man).
It is not known whether frovatriptan will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
It may not be safe to breast-feed while using this medicine. Ask your doctor about any risk.
Frovatriptan is not approved for use by anyone younger than 18 years old.
How should I use frovatriptan?
You may receive your first dose in a hospital or clinic setting to quickly treat any serious side effects.
Take frovatriptan as soon as you notice headache symptoms. Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Never use more than your recommended dose. Overuse of migraine headache medicine can make headaches worse. Tell your doctor if the medicine seems to stop working as well in treating your migraine attacks.
Take 1 tablet whole with a full glass of water.
After taking a tablet: If your headache does not completely go away, call your doctor before taking a second tablet. If your headache goes away and then comes back, take a second tablet if it has been at least 2 hours since your first tablet. Do not take more than 3 tablets in 24 hours.
Call your doctor if your headache does not go away at all after taking the first frovatriptan tablet.
Tell your doctor if you have more than four headaches in one month (30 days). Tell your doctor if this medicine seems to stop working as well in treating your migraine attacks.
Store at room temperature away from moisture and heat.
What happens if I miss a dose?
Since frovatriptan is used when needed, it does not have a daily dosing schedule. Call your doctor if your symptoms do not improve after using frovatriptan.
What happens if I overdose?
Seek emergency medical attention or call 115.
What should I avoid while using frovatriptan?
Do not take frovatriptan within 24 hours before or after using another migraine headache medicine, including:
sumatriptan, almotriptan, eletriptan, naratriptan, rizatriptan, zolmitriptan; or
ergot medicine such as dihydroergotamine, ergotamine, ergonovine, or methylergonovine.
Avoid driving or hazardous activity until you know how frovatriptan will affect you. Your reactions could be impaired.
